Inheritance of resistance to Alternaria blight of wheat was studied in a set of diallel crosses of 8 parents involving 7 resistant parents Agra Local, NP 52, NP 824, NP 4, NP 809, E 1912 and E 581 and a susceptible parent, NP 830. Resistance to leaf blight was governed by a pair of recessive genes in the varieties, Agra Local, NP 52 and NP 4 and by two pairs of recessive genes in varieties NP 824 and NP 809. In varieties Timenstein × Mida (E 1912) and Kenya 184. P.2. A.I.F. (E 581) resistance was controlled by three and one pair of dominant genes, respectively.
